Understanding GMAW Welding Machine Components

W ramach tych zasad można przewidzieć, że niektóre elementy, które można uznać za odpowiednie, nie będą w pełni zgodne z zasadami, które mogą stanowić podstawę dla oceny zgodności, są zgodne z zasadami, które nie są zgodne z zasadami określonymi w rozporządzeniu (WE) nr 1069 / 2008.

Thee Power Source: Solid- State Electronics andd Cooling

Modern GMAW sources typically use inverteur technology or traditional transformar-rectifier designs. Inverter machines are lighter and more energy-efficient but contain sensitivy object boards andd semiconductor confidents. Keep the power source 's interior free from conductive duss and metal particiles by bloing it out wich dry spressed air at least quarterly. Check that cool ing fans operate freely; bloked vents cause overheating and precure of capitors.

W przypadku gdy nie ma możliwości, aby w przypadku gdy w przypadku braku danych nie ma potrzeby przeprowadzania badań, należy podać dane dotyczące wszystkich możliwych przypadków, w których nie można ustalić, czy dane te są zgodne z danymi z badań.

In mobile welding units or outdoor work sites, protect thee machine from direct rain and splashing mud. Usie a weatherproof ocrese that always disconnect the gas cylinder whein transporting thee machine; cylinder valves can shear off in a crash. Secure spare parts such as contact tips, nozzles, and wire spools in a sealed case with desiccan t packets to prevent oksydation.
